Abstract:

This paper presents a new anthropometrics-based method for generating realistic, controllable face models. Our method establishes an intuitive and efficient interface to facilitate procedures for interactive 3D face modeling and editing. It takes 3D face scans as examples in order to exploit the variations presented in the real faces of individuals. The system automatically learns a model prior from the data-sets of example meshes of facial features using principal component analysis (PCA) and uses it to regulate the naturalness of synthesized faces. For each facial feature, we compute a set of anthropometric measurements to parameterize the example meshes into a measurement space. Using PCA coefficients as a compact shape representation, we formulate the face modeling problem in a scattered data interpolation framework which takes the user-specified anthropometric parameters as input. Solving the interpolation problem in a reduced subspace allows us to generate a natural face shape that satisfies the user-specified constraints. At runtime, the new face shape can be generated at an interactive rate. We demonstrate the utility of our method by presenting several applications, including analysis of facial features of subjects in different race groups, facial feature transfer, and adapting face models to a particular population group.

Abstract:

Human subjects are able to identify the sex of faces with very high accuracy. Using photographs of adults in which hair was concealed by a swimming cap, subjects performed with 96% accuracy. Previous work has identified a number of dimensions on which the faces of men and women differ. An attempt to combine these dimensions into a single function to classify male and female faces reliably is described. Photographs were taken of 91 male and 88 female faces in full face and profile. These were measured in several ways: (i) simple distances between key points in the pictures; (ii) ratios and angles formed between key points in the pictures; (iii) three-dimensional (3-D) distances derived by combination of full-face and profile photographs. Discriminant function analysis showed that the best discriminators were derived from simple distance measurements in the full face (85% accuracy with 12 variables) and 3-D distances (85% accuracy with 6 variables). Combining measures taken from the picture plane with those derived in 3-D produced a discriminator approaching human performance (94% accuracy with 16 variables). Performance of the discriminant function was compared with that of human perceivers and found to be correlated, but far from perfectly. The difficulty of deriving a reliable function to distinguish between the sexes is discussed with reference to the development of automatic face-processing programs in machine vision. It is argued that such systems will need to incorporate an understanding of the stimuli if they are to be effective.

Abstract:

AbstractThough controversial, the “clock face view” of the intercondylar notch remains a way some surgeons communicate regarding placement of the femoral tunnel in anterior cruciate ligament reconstruction. The purpose of this study was to quantify the differences in angle measurement between several previous descriptions of the clock face view by using a new reference standard. Three-Tesla magnetic resonance imaging (MRI) was used to scan 10 human knees to create three-dimensional MRI-based bony models which were used for measurements. A standardized clock face view was developed with the knee flexed to 90° using the junction of the cartilage and cortex of the medial and lateral surfaces of medial and lateral femoral condyles as the 3 o'clock and 9 o'clock, respectively, with the 12 o'clock established as the midpoint of the roof of the intercondylar notch. With the knee viewed at 90° of flexion, an “idealized” femoral tunnel position was plotted on the medial wall of the lateral femoral condyle at 30° (corresponding to the 10 o'clock or 2 o'clock position). The clock faces as described by Edwards et al, Heming et al, and Mochizuki et al were each then overlaid on this same model and the difference in measurement calculated. The average angles measured when the previously described clock faces were projected onto the idealized clock face view comparing a mark made at 30° were 47.7°, 7.2°, and 49.8° for the methods described by Edwards et al, Heming et al, and Mochizuki et al, respectively (all p < 0.001). Significant variation exists between angle measurements in simulated femoral tunnel placement based on the varying descriptions of the intercondylar clock face.

Abstract:

Newtonian reaction to blood influx into the head at each heartbeat causes subtle head motion at the same frequency as the heartbeats. Thus, this head motion can be used to estimate the heart rate. Several studies have shown that heart rates can be measured accurately by tracking head motion using a desktop computer with a static camera. However, implementation of vision-based head motion tracking on smartphones demonstrated limited accuracy due to the hand-shaking problem caused by the non-static camera. The hand-shaking problem could not be handled effectively with only the frontal camera images. It also required a more accurate method to measure the periodicity of noisy signals. Therefore, this study proposes an improved head-motion-based heart-rate monitoring system using smartphones. To address the hand-shaking problem, the proposed system leverages the front and rear cameras available in most smartphones and dedicates each camera to tracking facial features that correspond to head motion and background features that correspond to hand-shaking. Then, the locations of facial features are adjusted using the average point of the background features. In addition, a correlation-based signal periodicity computation method is proposed to accurately separate the true heart-rate-related component from the head motion signal. The proposed system demonstrates improved accuracy (i.e., lower mean errors in heart-rate measurement) compared to conventional head-motion-based systems, and the accuracy is sufficient for daily heart-rate monitoring.

Abstract:

Surface roughness is of great importance in the manufacturing industry, as it affects surfaces’ tribological properties (wear, friction, lubrication, etc.), corrosion resistance, fatigue strength and appearance. Areal roughness measurement, which provides a more comprehensive characterization of surfaces, is becoming increasingly popular, but systematic studies are still lacking, so measurements are often analyzed differently. In this paper, the effect of the measurement length is analyzed in the main measurement direction on areal roughness of face milled surface topographies, which were measured with a confocal chromatic sensor.

Abstract:

Diamond is arguably the best candidate material for heat dissipation applications, especially in high-power electronic devices. Silicon carbide (SiC) is a kind of wide band gap material, which can be used in applications of silicon (Si) components to reach the performance limits. In this paper, thin diamond films were successfully deposited on C-face and Si-face of 6H-SiC substrates respectively using MPCVD at temperatures from 800 to 1050 °C. SEM images indicated the growth quality comparison of the two faces of SiC. The diffraction peaks of the diamond (111), (220), and (311) crystal planes can be observed by XRD measurement, and the intensity of the diamond diffraction peaks grown on the C-face is stronger than that on Si-face. The growth process was analyzed by Raman spectrum. FWHM of diamond Raman spectra on Si-face and C-face are 6.07cm-1 and 5.47cm-1 respectively. All above measurement results show that the diamond grown on the C-face has higher crystal quality than that on Si-face of SiC.

Abstract:

Contact behavior in a public space influences the risk of contact infection because public spaces have many environmental surfaces contaminated with pathogens. It is useful for risk reduction to examine the factor of infection risk among behaviors. In the present study, a video monitoring survey was conducted in a simulated cabin of a commuter train, we had built, to investigate the relationship between face-touching frequencies and individual attributes. As a result, the average face-touching frequency was 17.8 times per hour. Of all face touches, mucosal contact was 42.2%. Focusing on the sex, the face-touching frequency was significantly higher for the males than for the females. Focusing on the skin condition, the face-touching frequency of those who did not wear makeup was significantly higher than that of those who did. The significant sex differences may depend on the makeup. Focusing on pollution awareness, higher pollution awareness related to lower frequency. Thus, by improving pollution awareness of the environmental surfaces in public spaces, it is possible to reduce effectively face-touching frequency and, hence, infection risk.

Abstract:

We assessed the feasibility of obtaining probe microphone measurements of hearing aids at a distance. Face-to-face and remote probe microphone measurements were carried out in 60 hearing aid users (mean age 67 yrs) with uni- or bilateral hearing losses (105 ears tested). The participant and a facilitator were located in a room equipped with a probe microphone system interfaced to a PC. Desktop videoconferencing and application sharing was used to allow an audiologist in another room to instruct the facilitator and control the equipment via the LAN. There were significant correlations between face-to-face and remote real ear unaided response (REUR), aided response (REAR) and insertion gain (REIG) at seven discrete frequencies from 250 to 6000 Hz. Differences between face-to-face and remote responses were within the reported variability for probe microphone measurements themselves. The results show that remote probe microphone measurements are feasible and might improve the quality of public hearing aid services and professional training in Brazil.

In this paper, a matrix based feature extraction and measurement method, i.e.: multi-column principle component analysis (MCPCA) is used to directly and effectively extract features from the matrix. We analyze the advantages of MCPCA over the conventional principal component analysis (PCA) and two-dimensional PCA (2DPCA), and we have successfully applied it into face image recognition. Extensive face recognition experiments illustrate that the proposed method obtains high accuracy, and it is more robust than previous conventional face recognition methods.

Abstract:

Heart rate, the speed of the heartbeat, has been regarded as one of the most important measurements to evaluate one’s health. It can be used to measure one’s anxiety, stress and illness; abnormalities of heart rate usually indicate potential disease one may have. Recent studies have shown that it is possible to directly measure the heart rate from a sequence of images that contain a person’s face. Requiring only a webcam, this method largely simplifies the process of traditional methods, which require the use of a pulse oximeter attached to the fingertip to measure the PPG signal, or electrodes placed on the skin to measure the ECG signal. However, this most recent method, though attracting a lot of interest, still suffers from sudden movement of the head, or turning away from the camera. In this paper, we propose a novel robust method of generating reliable PPG signals and measuring the heart rate from only face videos in real time, which is invariant to the movement of the head. We have also conducted studies on how different factors, light conditions, the angle of the head and the distance of the head away from the camera, could affect the predictions of the heart rate. After conducting a thorough analysis, we can conclude that our method succeeds in producing accurate, robust and promising results.

Abstract:

Abstract Recent research has attempted to examine the proportion of interviewer variance that is due to interviewers systematically varying in their success in obtaining cooperation from respondents with varying characteristics (i.e., nonresponse error variance), rather than variance among interviewers in systematic measurement difficulties (i.e., measurement error variance) - that is, whether correlated responses within interviewers arise due to variance among interviewers in the pools of respondents recruited, or variance in interviewer-specific mean response biases. Unfortunately, work to date has only considered data from a CATI survey, and thus suffers from two limitations: Interviewer effects are commonly much smaller in CATI surveys, and, more importantly, sample units are often contacted by several CATI interviewers before a final outcome (response or final refusal) is achieved. The latter introduces difficulties in assigning nonrespondents to interviewers, and thus interviewer variance components are only estimable under strong assumptions. This study aims to replicate this initial work, analyzing data from a national CAPI survey in Germany where CAPI interviewers were responsible for working a fixed subset of cases.

Abstract:

Irradiation of crystalline materials by neutrons or other energetic particles often causes swelling by formation of internal cavities, or voids. The swelling, or total void volume within a given sample volume, can be determined from transmission electron micrographs by simple measurement of the void images. However, errors of over 100% in the calculated void volumes are possible if the voids are approximated as spheres. The problem arises because the voids are usually polyhedral, crystallographically oriented features and no single size parameter has been defined for the spherical approximation. In austenitic stainless steels and other face-centered-cubic (fCC) alloys, voids range from octahedra with {111} faces to cubes with {100} faces and exhibit all intermediate (truncated) forms. Void truncation may also vary widely within a given field of view. Voids in ferritic steels and other body-centered-cubic (bcc) materials may range from octahedra with {111} faces to cubes with {100} faces to dodecahedra with {110} faces. The relationship between void shape on electron micrographs and void volume was therefore studied with the aim of improving the accuracy of swelling determination without requiring a separate shape determination for each void. Void volumes were determined as a function of a shape parameter and related to the various ‘size’ parameters available in different crystal orientations. Procedures were then defined to minimize the error in swelling measurement.

Abstract:

A technique for automated face detection and its pose estimation using single image is developed. The algorithm includes: face detection, facial features localization, face/background segmentation, face pose estimation, image transformation to frontal view. Automatic face/background segmentation is performed by original graph-cut technique based on detected feature points. The precision of face orientation estimation based on monocular digital imagery is addressed. The approach for precision estimation is developed based on comparison of synthesized facial 2D images and scanned face 3D model. The software for modelling and measurement is developed. The special system for non-contact measurements is created. Required set of 3D real face models and colour facial textures is obtained using this system. The precision estimation results demonstrate the precision of face pose estimation enough for further successful face recognition.

Our conclusion is that, in this instance, it is inappropriate to replace the traditional face-to-face methodology with a wholly online solution, but that, instead, a multi-modal approach that combines face-to-face with online interviewing is the way forward.

Abstract:

Background: The description of the human face has been a major concern since long time. Individual identification is one such field where anthropometric parameters, especially cephalo-facial measurements, are an important tool in determining the various shapes of head and face. Hence the objective of the study was to determine the shapes of head and face. Methods: The present study was a cross-sectional and observational type which consisted of 222 individuals (115 female and 107 male). It was conducted from January to June, 2019 after receiving ethical approval. The cephalic and facial indices were derived after measuring length and breadth of head and face. The collected data was entered in excel and analyzed with SPSS (22.0). Results: The present study observed that the most common type of face was hyperleptoprosopic 168 (75.68%) followed by leptoprosopic 43 (19.37%), mesoprosopic 10 (4.50% female only) and euryprosopic 1 (0.93% male only). Similarly, the most common type of head was dolicocephalic 165 (74.33%), followed by mesocephalic 51 (22.97%), and brachycephalic 6 (2.70%). Conclusions: This study concluded that the hyperleptoprosopic face was most common type and the least common type was euryprosopic face. The most common type of head was found to be dolicocephalic and the least common type was found to be brachycephalic.

Abstract:

A modern approach to clinical skill education is the use of educational videos, yet there is a shortage of literature investigating the effect of self-instruction videos (SIVs) in pharmacy students. Therefore, our objective was to investigate whether an SIV is non-inferior compared to face-to-face instruction (FTFI) in acquiring blood pressure measurement skills. The participants in this randomized controlled study were pharmacy students. The control group was taught by FTFI, while the intervention group watched an SIV. Before and after the instruction, the participants’ performance was assessed by an objective structured clinical examination (OSCE). The participants completed a self-assessment survey before each OSCE session. Moreover, the participants’ perception and satisfaction were assessed using another survey. The OSCE score and self-assessment score increased significantly from pre- to post-instruction in both groups. The SIV was non-inferior compared to FTFI in terms of the OSCE score, considering a predefined non-inferiority margin of −10%. The participants’ self-assessment yielded inconclusive results for non-inferiority. Both instructional approaches were well received. Considering our findings, SIVs might be a valuable option for teaching pharmacy students’ blood pressure measurement skills. However, depending on the skill intended to be taught, a combination of an instructional video with instructor-led teaching may be necessary.

Abstract:

<p style="text-align: justify;">This study explored the cognitive mechanism behind information integration in the test anxiety judgments in 140 engineering students. An experiment was designed to test four factors combined (test goal orientation, test cognitive functioning level, test difficulty and test mode). The experimental task required participants to read 36 scenarios, one at a time and then estimate how much test anxiety they would experience in the evaluation situation described in each scenario. The results indicate three response styles (low, moderate, and high-test anxiety) among the participants. The orientation and difficulty of each given exam scenario were the most critical factors dictating test anxiety judgments. Only the moderate test anxiety group considered the test mode to be a third relevant factor. The integration mechanism for Cluster 1 was multiplicative, while for Clusters 2 and 3, it was summative. Furthermore, these last two clusters differed in terms of the valuation of the factors. These results suggest that programs that help students to cope with test anxiety need to take into account the valuation and integration mechanism that students use to integrate different information in specific examination contexts, since the way students assess their internal and external circumstances can influence how they deal with evaluative situations.</p>

Abstract:

A wide range of applications can benefit from the measurement of facial activity. The current study presents a method that can be used to detect and classify the movements of different parts of the face and the expressions the movements form. The method is based on capacitive measurement of facial movements. It uses principal component analysis on the measured data to identify active areas of the face in offline analysis, and hierarchical clustering as a basis for classifying the movements offline and in real-time. Experiments involving a set of voluntary facial movements were carried out with 10 participants. The results show that the principal component analysis of the measured data could be applied with almost perfect performance to offline mapping of the vertical location of the facial activity of movements such as raising and lowering eyebrows, opening mouth, raising mouth corners, and lowering mouth corners. The presented classification method also performed very well in classifying the same movements both with the offline and the real-time implementations.

Abstract:

The linearity of response of X-ray detectors is tested. Examples of linearity tests demonstrate the remarkable range of linear response of flowing-gas ion chambers in the synchrotron environment. The diagnostic is also highly sensitive to the presence in the X-ray beam of harmonic X-rays diffracted by a higher-order reflection of the monochromator. The remarkable range of linearity of ion chambers has enabled the accurate measurement of the absolute X-ray attenuation of a number of elements. It should now be possible to measure the absolute intensity of Bragg reflections, provided such measurements are carried out with extended-face single crystals. The advantages of the extended-face crystal technique for Bragg intensity measurements are summarized and a number of approaches to absolute Bragg intensity measurement are discussed.

Abstract:

ABSTRACTIn this work we develop and validate a model measuring norms that distinguish three types of culture: dignity, face, and honor (Leung & Cohen, 2011). Our motivation is to produce empirical evidence for this new cultural framework and use the framework to explain cultural differences in interdependent social interactions such as negotiation. In two studies, we establish the content validity, construct validity, predictive validity, and measurement invariance of this measurement model. In Study 1, we present the model's three-factor structure and situate the constructs of dignity, face, and honor in a nomological network of cultural constructs. In Study 2, which uses a sample of participants from 26 cultures, we show that the measurement model discriminates among people from the three cultural regions corresponding to the dignity, face, and honor framework. In particular, we report differences between face and honor cultures, which are not distinguished in other cultural frameworks (e.g., Hofstede, 1980). We also show that the measurement model accounts for cultural differences in norms for use of negotiation strategy.
